IAP274 External antenna selection



Hi guys,

I usually offer IAP275 for outdoor integrated OMNI antenna while IAP277 for outdoor integrated directional antenna. However some clients prefer deploying external antenna in which I’m having difficulty in recommending and consolidating these antennas according to purpose.

Below is my attempt to sort them according to docs.Any corrections or suggestions are greatly appreciated.



*directional antenna, (check datasheet for beamwidths)*

2.4Ghz for client serving like street, spot coverage etc

ANT-2x2-2314

2.4/5Ghz sector wi-fi converage

ANT-3x3-D608

ANT-3x3-D100

5Ghz P2P connections

ANT-2x2-5314 (p2P)

ANT-3x3-5712 (point to multipoint) mesh connections

2.4Ghz 802.11nMIMO mesh link applications

ANT-2x2-2714

My question is how to determine the required qty of antenna per AP and its lightning arrestors?

I’m also referring to AP270 ordering guide

Re: IAP274 External antenna selection

A quick note, generally speaking we don't recommend any high gain antennas for client coverage, the 2x2-2314/2x2.2714 are mostly for limited mesh purposes in countrys where 5Ghz is disallowed. 

 

To the question on the number of antennas, the 274 is a 3x3 AP, which means there are three connectors per radio. You CAN use a 2x2 antenna on a 3x3 AP, you just put the antenna on ANT0/ANT1, and have to put a 50 ohm terminator on the unused connector ANT2 for whatever radio the 2x2 antenna is placed on.
